Man United boss reveals why he made his second change after only 39 minutes

Louis van Gaal has come out to defend his decision to take off a fully fit Paddy McNair just after 39 minutes despite the fact that it was his second substitution in the first half after earlier losing Chris Smalling to injury, Daily Mail reports.

The 19-year-old was unable to cope with the continuous attacking plays from the Southampton forwards as both Shane Long and Graziano Pelle were overpowering the young centre-back on all fronts.
